Very very very long. Unnecessarily long. Has taken almost a year now and still awaiting feedback. They start with written interviews two stages and then a panel interview. If well prepared it's not too difficult.

An online application is first submitted and a couple of months wait for the first contact from HR. Then a first online written test of about 1hr 30mins-2 hours maximum for preselection followed by a panel interview. Selected candidates are interviewed by a panel of 5-6 interviewers. There is in most cases a two week interval between test, interview and Offer of employment.
